SIDE CASTING.

Specification of Letters Patent.

Patented-Jan. 7, 1919.

To all whom t may concern:

Be it known that I, JOHN F. OCoNNoR, a

residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Side Castingsz of which the following is a full, clear, concise, and exact description, reference being had to the aecompanying drawings, forming a part of this specification.

This invention relates to improvements in side castings.

The object of the `invention is to provide a side casting for railway draft riggings which is of great strength per unit weight of metal, which is of substantially uniform thickness throughout and at the same time free from T-sections, which is so designed that chills or feeders during the molding are rendered unnecessary, which is reversible, which provides large abutment areas, and wherein thc rivet holes are ideally located for actual service conditions.

In the drawing forming a part of this specification, Figure 1 is a side elevation of a stop or side casting embodying my invention. Fig. 2 is a top plan view of the strueture illustrated in Fig. 1. And Figs. 3, 4, 5 and 6 are vertical, sectional views, taken on the lines 3-3, 4-4, 5-5 and 6 6, respectively, of Fig` 1.

In said drawing, the stop casting which I have illustrated is of the tandem type havingl front main stop shoulder 10, front intermediate stop Shoulder 11, rear intermediate stop shoulder 12, and rear main Stop shoulderll. Corresponding limitin stop shoulders 14, 15, 16 and 17 are provi ed to limit the movements of the followers in a Well known inanner. The said stop elusive nre formed hy extending the web w of the casting inwardly and outwardly in the` form of vertical convolutions, as clearly appears from the top plan View shown in Fig. 2, said convolutions being faced alternately inwardly and outwardly.

The web of the casting is also extended horizontally to form an upper flange 18 which is extended to the back lane of the casting and at the bottom la simi ar flange 19 is formed.

In order tov provide great strength in the casting and accomplish the other objects of the invention above enumerated, I provide a sei-ies of parallel, diagonally extending con- `volutions 20, 21, 22,

shoulders 10 to 17 in- 23 and 24. These convolutions have their adjacent ends overlapped when viewed in a vertical plane, as clearly and each of said diagonal convolutions 20 to 24 rhas the bottom thereof extended to the back plane of .the casting so as to form a suitable riveting area and it is of course evident that each of said diagonal convolutions 20 to 24 is open to the inner side of the casting. Each diagonal convolution is extended through or across an abutment utilized for forming one or more of the main or limiting stop shoulders. In this manner, the abutting face or stop shoulder for each of the stops is reinforced by upper and lower horizontally extending flanges and two diagonallyr extending flanges, that is to say, four strengthening flanges, two of which are horizontal and two diagonel, whereby reat resistance is afforded for the stop shou ders.

At their ends, each of the diagonal convolutions 20 to 24 is circularly enlarged, as indicated at 25-25, t0 thereby provide suffieient space for the head of a riveting tool the rivet holes being located at the ends o said diagonal convolutions, as indicated at 26. The three intermediate convolutions 21, 22 and 23 are similarly cii'cularly enlarged at their centers, as indicated at 27-27 and for the same purpose,1 there being` provided three rivet holes 28-28 at the centers of said convolutions, as clearly indicated in Fig. 1. At diagonally opposed corners of the casting, circular depressions 29--29 are formed fortwo additional rivets, the arrangement being such that there are six rivet holes proa'ppears from Fig. 1,

vided in each of two substantially parallel u per and lower'lines and three rivet holes a ong` a central longitudinally extending line. By this method, I provide 15 rivet holes well distributed both casting and vertically thereof so as to avoid any concentration of the rivet holes or riveting areas in any single line of resistance.

The casting, above described, is obviously of substantially uniform thickness throughout its entirety and of substantially uniform weight per unit of length. Obviously also the casting may be reversed and used with either edge uppermost, thereby minimizing the number of parts which railroads are required to carry in stock for repairs.

T claim:
